Issue

• What happens if I am editing a thread or message on the BBS widget and the session expires without posting, what happens if I press "publish"?

Environment

• DXP 7.0+

solution

• If you are editing a thread or message on the bulletin board portlet and your session expires without posting, press "Publish" to go to the login screen.
• If you log in again, the following warning message will be thrown because the current session information cannot be used to authenticate access to the original screen.
  WARN [ajp-nio-41304-exec-138][SecurityPortletContainerWrapper:348] User XXXXX is not allowed to access URL http://XXX/ and portlet com_liferay_message_boards_web_ portlet_MBPortlet
• When the user logs in again, a new session is created.
  Because the session IDs do not match, the "unpublished edits" associated with the old session ID are discarded.This is an action to prevent CSRF attacks.
• When accessing a page that requires authentication while the session is expired, the user will be redirected to the login screen.
